so, he wanted to know about the "engine" not the pull start, if it's the same engine (without the pull start and Heli head) couldn't he get some info from that video

here is the info he listed,,
I run the MECOA .46 with 6 different props;
1) 9x6 Zinger,
2) 9x7 Master Airscrew,
3) 9x8 REV-UP Pylon,
4) 10x6 APC,
5) 10x7 Master Airscrew
6) 11x6 APC.

Fuel was 15%. The air temp. was 40 degrees. An OS A3 glow plug was used. Engine is ABC construction with Schnuerle porting and a boost port. Advertised HP is 1.4 at 17,000 rpm with a tuned pipe and 20%.

Results:
1) 9x6 14700,
2) 9x7 15000,
3) 9x8 13980,
4) 10x6 13470,
5) 10x7 13470,
6) 11x6 11280.

The Master Airscrew props run faster because they flex.


looks like some good info there
